ChatCoal made up more than 80% of retired electricity generating
Coal made up more than 80% of retired electricity generating capacity in 2015. Nearly 18 gigawatts (GW) of electric generating capacity was retired in 2015, a relatively high amount compared with recent years. More than 80% of the retired capacity was conventional steam coal. The coal-fired generating units retired in 2015 tended to be older and smaller in capacity than the coal generation fleet that continues to operate.
